Tarsal Coalition, Calcaneonavicular, Left Foot, Congenital

ICD-10 Code
Q74.2_2

Abnormal connection between two or more bones in the left midfoot/hindfoot, present from birth.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with chronic left foot pain, localized to the midfoot/hindfoot, exacerbated by weight-bearing activities and uneven terrain. History of progressive stiffness and recurrent ankle sprains. No history of acute trauma. Symptoms are consistent with congenital calcaneonavicular coalition.

Clinical Examination Findings

Left foot examination reveals a rigid flatfoot deformity with restricted subtalar joint motion. Tenderness noted over the calcaneonavicular joint interval. "Anteater nose" sign may be present on radiographic imaging. Gait analysis shows decreased hindfoot eversion/inversion during the stance phase.

Treatment Protocol

Initial management includes activity modification, orthotic arch support, and non-steroidal anti-inflammatory drugs (NSAIDs). If conservative measures fail, consider physical therapy for range of motion or surgical intervention (resection of the coalition with interposition of fat/muscle graft or arthrodesis).
